This invention relates to a "storage brushless DC motor" circuit device, especially a power supply using a power storage device and a micro-control device to a brushless DC motor, so that the micro-control device can be controlled and the DC The power supply can supply power indirectly, the power storage device can store power and make the storage battery can directly supply power, so as to reach the motor circuit device of the brushless DC motor that can store power, can be powered by power, or can be free of power.

According to this, in the era of unstable power supply sources, the cost of power supply-related energy may increase. At the same time, for the consideration of the global environment, to avoid dramatic changes in the environment due to excessive carbon dioxide emissions from power supply, all parties advocate power regulation, energy saving and carbon reduction Related practices. Among them, the innovative and efficient use of power supply to the motor is a specific method of power regulation.

The conventional brushless DC motor uses the power supply to drive the load. Please refer to the first figure. One of the brushless DC motor 01 consists of a coil group 011, a coil group 012, a coil group 2 013, a Coil group two 014, a coil group three 015, a coil group three 016 and an N magnet 017, an S magnet 018, the brushless DC motor 01 uses a DC power supply to the coil group one 011, coil group one 012, the coil group two 013, the coil group two 014, the coil group three 015, the coil group three 016, and using a Hall induction device, can drive the N magnet 017 and the S magnet 018 to rotate and drive through a rotating shaft 019 One load work. During normal operation of the load, the DC power supply is a full time power supply, so that the brushless DC motor 01 can continuously provide the driving kinetic energy of the load.

However, the statistics of IEK in April 2014 show that the general motor power consumption accounts for about 46% of the global power consumption. Prolonged or continuous use of power supplies (such as municipal power) to supply power to the motor will cause considerable Power supply load, the power supply is not able to take into account the requirements of power regulation; on the other hand, the brushless DC motor is widely used in daily life and industry, and the use of commercial power as the motor power source, the brushless DC motor power consumption accounted for In addition, the general motor consumes a lot of power. Therefore, the innovation of the brushless DC motor (industrial equipment, household equipment) using the mains power supply is also the research direction and effort goal of the motor and motor manufacturing.

In view of the shortcomings of the power consumption and power load of various brushless DC motors derived from the foregoing prior art, the inventor of this case is eager to improve and innovate, and after many days of painstaking research, he finally successfully developed a "Brushless DC motor" circuit device.

The purpose of the creation of this invention is to provide a brushless DC motor circuit device that can store electricity, be powered by a power supply, or can be used without a power supply. The concept is that a brushless DC motor can be provided with a power storage device and a micro-control device, so that The micro-control device can be operated and the DC power supply can indirectly supply power to the brushless DC motor, or the power storage device can store electricity and allow a battery to directly supply power to the brushless DC motor to achieve the brushless DC The motor can store electricity, can be powered by power, or can use power without electricity, and can meet the power supply requirements of power regulation.

In order to achieve the above purpose, the technical means of the present invention is to provide a power storage device inside a brushless DC motor and a micro-control device outside the brushless DC motor to form a "storable brushless DC" "Motor" is a chargeable DC motor. The power storage brushless DC motor is provided with a motor electromagnet stator (or coil group stator) composed of a multi-pole coil group and a motor permanent magnet rotor (or N magnet rotor, composed of N magnets and S magnets). S-magnet rotor), the motor permanent magnet rotor can be mechanically connected to a load outside the brushless DC motor through a rotating shaft; the power storage device of the brushless DC motor can be equipped with a flexible motor battery and multiple liters Voltage switch circuit, the flexible motor battery can be connected to a DC power source (eg, transformer, power supply) external to the rechargeable brushless DC motor, and the plurality of boost switch circuits are electrically connected to the multi-pole coil group Connected; and, the micro-control device of the power storage brushless DC motor is provided with a DC-DC converter (DC to DC converter) and a microprocessor, the DC-DC converter and the power storage brushless DC motor outside The DC power supply and the flexible motor battery of the power storage device are electrically connected, and the microprocessor is electrically connected to the DC-DC converter and the plurality of booster switch circuits of the power storage device.

The brushless DC motor that can store electricity can be controlled by the microprocessor of the micro-controller. A DC power supply outside the brushless DC motor that can store electricity is converted by a DC-DC converter to supply power to the flexible motor battery of the power storage device (battery storage ), the flexible motor battery is transformed through a plurality of boost switch circuits and then supplied to the stator of the coil group composed of the multi-pole coil group to drive the rotation of the N magnet rotor and S magnet rotor composed of N magnets and S magnets (The external DC power supply indirectly powers the motor) and drives the load to work. When the N-magnet rotor and S-magnet rotor rotate to work, the external DC power supply can continue to supply power to the flexible motor battery (the battery continues to store electricity); The micro-control device of the brushless DC motor can be controlled and the DC power supply outside the brushless DC motor can be indirectly supplied to the brushable DC motor for rotation.

Alternatively, the power storage brushless DC motor can be controlled by the microprocessor of the micro-control device to dispense with the external DC power supply of the power storage brushless DC motor, and only utilizes the flexible motor battery of the power storage device through multiple boost switches The stator of the coil group composed of the circuit and the multi-pole coil group drives the N magnet rotor and S magnet rotor composed of N magnets and S magnets to rotate (the internal battery directly supplies the motor) and drives the load to work. When the N magnet rotor and S magnet rotor During the rotating operation, the external DC power supply can stop supplying power to the flexible motor battery (the battery stops storing), and does not affect the normal operation of the load; therefore, the power storage device of the brushless DC motor can store power and make The flexible motor battery inside the brushless DC motor that can store electricity can directly supply power to the brushless DC motor that can store electricity to rotate and work.

In this way, in the creation of this invention, a "storable brushless DC motor" composed of a brushless DC motor, a power storage device, and a micro-control device can be controlled and the DC power supply can be indirectly supplied to The brushless DC motor rotates to work, or the power storage device can store electricity and allow the motor battery to directly supply power to the brushless DC motor to rotate. Using this new type of motor battery-powered motor concept, the brushless DC motor can be achieved Innovative power consumption characteristics that can store electricity, can be powered by power, or can be free of power.
